Alright i'll try to include as much information as possible so you guys can maybe help point me in the right direction for this problem. Basically...it started about 2 1/2 weeks ago but the last thing I need is a big bill but i gotta fix her. Basically i used some injector cleaner and some of that premium shell vpower after a week but no luck there. While driving i sometimes feel like a lag in power for a couple seconds when acceleratin to 60 and its a horrible feeling. At stop lights, it makes something similar to a knocking noise to where i can feel it do a quick jerk sometimes. Some days it'll be good to me but other days it can be obnoxious when at a red light and I can't help but do anything to fix it.

Since this problem happened i've felt it wanna die but it'll revive itself back up real quick and it's only happened two or three times. The car is a 1997 se @ about 139k right now. Were the original owners so i am aware of its entire history. I still have 2k miles left before my next oil change and have already changed out a few things so hopefully this can eliminate the possibilities quicker. between 108k-115k i changed to ngk plat sparks, the pcv valve, knock sensor, radiator, and had a full service change with a flush. At 130k, my tranny died and i was forced to buy a new one ... then at about 137k, my starter died out on me too so that was brand new as well. I've never swapped my two o2's but i already have all new pipes underneath or the coils/injectors but haven't been an active enthusiast for a long time. It will also help to know i tried grabbing the code myself but was stumped when it only gave me 05 05, undefined as i checked it online..I guess a haynes manual would be nice. And for future reference, does anybody know some quality websites with a good selection of maxima parts? The one i've been using is www.autopartswarehouse.com and I think its pretty decent. Any help much appreciated.
